To all whomtt may concern:

Be it known that 1, Aims H. SMITH, a

citizen of the United States, residing in theborough of Bronznin thevcity of New York, county of Bronx, and State of New York, have invented certain new and useful Improvements in Perforating-Machines, of

, which the followingis a specification, reference being had therein to the accompany-.

ing drawings, whichform a part thereof.

My invention relates to perforating machines, and vmore particularly to a type is capable of being mechanically actuated,v

as distinguished from the present type of hand operated machines.

forating machine embodying therein a pair- A further object is to provide machine wherein the perforatingrollers will be rotated to a predetermined extentto secure the desired length of a' perforated line and will be automaticallyreversed or rotated in the opposite direction to accomplish the delivery of the sheet and avoid: mutilation thereof through a loss of'register of the punches with the already formedperforations.

A still further object is to provide a machine of this type which may be so adjusted or set as to adapt it for making lines of perforations of varying lengths, the adjustment determining the extent of rotative the paper sheets will be fed thereto through the perforating rollers by a mechanism controlled by and actuated in synchronism with said perforating rollers.

g The invention consists primarily in a perof perforating rollers, rotary main actuatying means, and operative connections bee means of an ordinary hand crank.

tween said. rollers and said main actuating meanswhereby said rollers are rotated in opposite directions alternately with: each full rotation of said actuating means; and. in such other novel features of construction andcombination of parts as are hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the .drawings:Figure lis a side elevation of a machine embodying, my invention, Fig. 2 is arrear elevation thereof; Fig' 3 is a detail cross. sectional view of the perforating rollers and the feed rollers; and Figs. 4 and 5 are detail views of the main actuating clutch mechanism.

Like letters refer to like parts throughouttheseveral views.- H

In the embodiment, of my invention shown inthe drawings, a indicatesthe main frame of the machine, in the top frame I) of which are. mounted the perforating rollers 0 and cl, the first of which carries the punches 0 and the other of which carries the die parts d. These rollers are of the ordinary and well known constructionyand such as have heretofore been. actuated by A i cent to said pair of rollers is; the feed shelf form of the invention shown in the drawings, will be more fully, referred to hereinafter. The rollers 0 and dare geared together by means of the gears 0 0Z 3 The perforating rollers, by my invention, instead of being hand actuated, are operated under mechanical power such as the main actuating mechanism, comprising the crank wheel 7, the driving wheel 9 and operative connections between said driving wheel and said crank wheel, and said crank 1 wheel and said rotary perforating rollers.

Inasmuch as in this type of machine, the sheets must be fed to the perforating rollers from the shelf 0 and delivered by said rollers to said shelf,it is necessary to pro- 'vide a structure wherein said rollers will be e, the-detailed construction ofwhich, in the 8 by the crank wheel 7 through the connecting rod Bythis construction, not only am I enabled to secure the desired accurate reversing of the direction of rotation of the perforating rollers, but avoid likelihood of injury to the sheets of paper to be perfo To adapt the machine to work requiring,

perforated lines of varying lengths, I provide means whereby the effective throw of the oscillatory gear segment 2' may be varied, thus permitting a variance in the quantity of rotative movement of the rotary perforators with each complete rotation of the main actuating means. To secure this result, I provide the segment 2' with a radially extending elongated slot 2', and mount the crank pin 7', upon which the rod j is mounted, in this slot in such manner as to permit its adjustment lengthwise thereof. I also provide the crank wheel f with a radially extending elongated slot f, in which the crank pin j upon which the other end of the rod j is mounted, is adjustably mounted. By this construction, I am enabled to secure practically any desired quantity of rotative movement of the perforating rollers c d, through a variance in the effective radii of the wheel or segment 2' upon which the connecting rod 7' acts.

Mounted upon the feed shelf 6 are the rollers 72 is, about which an endless flexible feeding sheet if passes. lhe first named of these rollers, 70, is mounted adjacent the perforating roller d,'and is driven therefrom and in synehronism therewith by means of the gear Z and the idler gear m inmesh therewith andwith the gear (Z Oppositely disposed to, and bearing upon, the feed roller is a second roller 72 adapted to be frictionally driven. The roller n is mounted in the pivoted arms a, and means are provided, as the cams o, rotating in synchronism with the perforating rollers 0 (Z, for actuating the arms a to raise the roller a prior to the initiation of the feeding movement of the roller 71'; upon the direct feed thereof, or of the backing out operation of the ma chine. These cams being mounted upon the shaft of the roller cl, the opening and closing of the rollers is synchronized with the operation of said perforating rollers.

l/Vhen a machine of the character herein described is in use, the driving wheel 9 is continuously rotated, and inasmuch as the operative relation of the sheet to be perforated toward the perforating rollers, is

manually controlled, it is desirable to provide means, under the control of the operator, whereby after each complete cycle of operations, the perforating rollers will be capable of automatic disconnection from driving wheel g. To secure this operative effect in the form of the invention shown, I mount upon the shaft f of the crank wheel f, a drum 20 having a recess in the periphery thereof, in which is seated a spring pressed pawl 79, having a normal tendency to move outward radially of said drum. Looselymounted upon said shaft f in close proximity to the drum 9, is the gear wheel 9, undercut as shown in Fig. l, the drum p projecting into said undercut portion. Said gear 9 on the'periphery of the undercut portion thereof, has a socket adapted to receive the pawl p, and thus transmit motion from said gear 9 to the drum 3) and the shaft 7. The pawl 72 is provided with a trip finger p projecting beyond the periphery of the gear Q, by means of which the outward projection of the said pawl 72 may be prevented.

Mounted in a fixed frame 1, adjacentthe drum p, is a contact pin 3 adapted to be normally projected into the path of the trip finger 32 Hence, under normal conditions, said pin will be in a position where it will prevent the pawl p from moving outwardly,

thus causing the gear 9 torun idly and transmit no movement to the perforating wheels. To cause the operation of the ma chine, I provide means as the bell crank lever 3 connected with the pin 3 and adapted to retract same out ofthe path of the trip linger 2%, whereby said pinmay be rendered inoperative to permit the pawl to move outwardly and transmit the desired power from the driving wheel 9- and its gear 9 through said clutch mechanism to the crank wheel 7 and the perforating rollers. This bell crank lever is under the control of an ordinary foot treadle. By this mechanism, the re lease of the foot treadle will have the effect of disconnecting the main driving wheel from the crank wheelvactuating means, but this disconnection will occur only upon the completion of any cycle of operations of the machine. Hence, the perforating rollers, when the machine is out of operation, will always come to rest at a certain point, and the machine must complete its full cycle of operations, or accomplish the delivery of the perforated sheet, before coming to rest.

The essential characteristics of the ma-- slow peripheral velocity in starting, to the maximum speed while the perforating is going on, and a gradually reduced speed to the point of reversal of the perforators for the hacking out operation. I

In connection with the above, I employ means for varying the quantity of operative movement of the perforating rollers with a main actuating mechanism, the operations of which are uniform and constant. The effective operation of the machine is increased by the particular feeding mechanism and the particular clutch mechanism heretofore described, which features, however, are of secondary importance in a machine of this character.

The operation of the herein described perforating machine is substantially as follows :When it is desired to start the machine, the treadle mechanism is actuated to cause the bell crank lever t to actuate the contact pin 8 in a manner to draw it with out the operative range of the trip finger p of the pawl g). The power from the main driving wheel 9 rotating the gear wheel 9 will, as the said gear wheel is rotated, bring the socket 9 thereof into operative relation to the pawl 12, which moving outwardly, will enter said socket and cause said gear Q to transmit movement to the block 3) and to the crank wheel f. When the'parts are at rest, the cams 0 will be in a position where they will raise'the arms a and the roller j a, thus afiording clearance between said feeding rollers to assist the feeder insecuring a timely and accurate feeding of each sheet. Prior to the setting of the clutch mechanism, a sheet of paper to be perforated is fed to a back gage upon the feeding shelf 6, withthe forward edge between the rollers n, thesheet resting. upon the belt 70 When power is applied to the crankwheel f, saidwheel will, through the connecting rod j, impart.

an oscillatory movement to the segmental rack 2', which, being 111 mesh with the gear it upon one of the perforating rollers, will impart a partial rotation to said perforating rollers, the extent of which rotation may be less than, exactly, or greater than, a full rotation thereof. The two rollers being geared together, will have simultaneous, equal movement. With the initiation of the rotary movement of the perforating rollers o d, the feed roller in will he turned by means of the gears Z 922, the peripheral velocity thereof being the same as that of the perforating rollers so that the paper will be fed'to said rollers speed which will minimize any tendency of the punchesto mutilateth-e paper. y

When the machine is at rest, the connectin rod is areferabl n 3011 a dead center thus insuring a starting of the feeding movement and the action of the perforators, at a low speed, bringing the speed up .to

maximum midway between centers, and gradually slowing the movement down so that at the end of the efiective operative movement of the perforate-rs, the connecting rod j will come to rest upon the opposite center, preparatory to a reversal of the oscillatory movement of the segment i toreverse the direction of rotation of the perforators and deliver the sheet by what is known as a backing out operation. This reverse rotation will have a variable speed in the same manner as in perforating. In hacking out, not only is the operation of the perforating rollers, reversed,-but the operation of the feeding mechanism is also reversed, and all mechanisms of the machine are reversed, ex cepting the main actuating mechanism, including the crank wheel f, which always rotates in the same direction in other words as unidirectional .rotary movement.

If it be desired to make the machine inoperative, it is merely necessary to release the treadle mechanism, or reverse the operation Y thereof, thus projecting the contact pin 8 within the path of the trip finger p so that as said trip finger comes into engagement with said pin, it will be retracted within the recess in the drum 7) and thus disconnect said drum from the gear 9 and permit said I gear to run idly. The advantage of this operation is that whatever the position of parts when the contact pin 8 isset to throw the machine out of operat1on, the machme will complete its cycle of operations before it stops, and when at rest, the different he made, and as a sequence of disks carry ing punches and dies usually makes up the perforating rollers, a plurality of such lines of perforations will be made simultaneoiisly.

By adjusting the crank pin 9 in the slot 2', or the crank pin j in the slot f,or by adjusting either or both of said crank pins, the operative throw of the connectingrod 7' upon the segmental rack i may be controlled in a manner to accurately determine the length of the line of perforations to he made by the perforating rollers 0 (Z, or in other words, the operative effect of the segmental rack-z" upon said perforators may be 0011-,

trolled through the radial adjustment of Furthermore, if desired,

the points of connection offthe connecting rod j with said segmental rack, or with the crank wheel f.- By this construction the same machine may be adjusted for making,v

difierent lengths of perforated lines.

To adapt the feeding mechanism to suchvariances in the quantity of rotativemove- &

ment of the perforating rollers, the cams 0 are adjusted circumferentially of the shaft of the perforating roller (Z, so that when the connecting rod j imparts initial movement to the rack 2', said cams will always be operative to raise the feed roller it out of the operative relation to the feed roller 7:. A machine of this type is adapted primarily to form a line of perforations extending along only a portion of the length of a sheet of paper, and the adjustment for controlling the lentgh of the lines of perforations formed, is important in this type of machine, while having no utility in connection with a machine in which perforations along the entire sheet are to be formed.

The backing out operation also is applicable only to a type of machine wherein the line of perforations does not extend for the entire length of the sheet being perforated, it being necessary, in delivering the sheet, to have each of the punches enter the perforation made thereby during the direct feeding movement of the sheet.

While the main actuating mechanism, including the crank wheel f, rotates continuously in one direction, the connecting rod j will impart an oscillatory movement to the segmental gear 71, and thus rotate the perforating rollers in opposite directions alternately, with each full rotation of said main actuating means.

By the mechanism herein described, I am enabled to produce a machine which will operate at uniform speeds during any cycle of operations thereof, wherein the succeeding sequence of operations will be accir rately timed and wherein succeeding sheets of paper may have perforated lines formed therein of uniform length, without likelihood of the overrunning of the perforators, or mutilation of the sheet thereby.

The timing of the feeding mechanism to and in accordance with the operative inter val of the perforating rollers, prevents any drag upon the paper which might tend toward a tearing thereof, and by reversing the rotation of the feeding mechanism during the backing out operation of the perforating rollers, I assist in the delivery of the sheet.

It is not my intention to limit myself to the precise details of construction shown in the accompanying drawings, it being apparent that such may be varied without departing from the spirit and scope of the invention.
